Coal burning cited as biggest cause of smog
Excessive use of “unclean” energy, mainly coal, is the main contributor to China’s recurrent smog, according to a Chinese expert quoted by China Youth Daily.
“Coal and other unclean energy sources are the number one contributor to China’s smog,” said Zhang Xiaoye, director of an atmospheric composition committee under the China Meteorological Society. Vehicle emissions may come second, especially in big cities, he told a symposium organized by the China Association for Science and Technology.
Citing PM 2.5 readings recorded in early November, when Beijing hosted the Asia-Pacific Economic Cooperation (APEC) meetings, Zhang said the figures showed a considerable drop of 35 percent, and only 10 percent of the reduction came from the odd-and-even license plate vehicle restrictions. (Photo 4)
